Comparing DNBP replacement options in styrene production
The manufacturing of styrene commonly uses 2,4-dinitro-6-sec butylphenol (DNBP) as a retarder to protect against styrene polymer formation.
Improve understanding of corrosion inhibitor technology for processing high-acid crudes
For corrosion risk assessment and control, ample published research exists on the inherent corrosivity of combinations of naphthenic acid and sulfur in refining systems, but not on the chemistry and mechanism of corrosion inhibitors. This work offers refinery engineers insight into the construction of corrosion inhibitor molecules, as well as how differences in molecules impact the performance of the inhibitor and the risk of fouling in crude units and hydroprocessing units.
